Worked on the cloudwego/hertz repository to improve the correctness and reliability of HTTP client redirect handling using Go. Addressed a critical bug where the Host header was not updated during HTTP redirects by ensuring the Host is now derived from the redirect Location header, which prevents misrouting and improves interoperability with downstream services and caching proxies. Developed automated regression tests to validate the new redirect behavior and safeguard against future regressions. Focused on HTTP client logic, redirect handling, and robust testing practices, while also enhancing documentation and CI readiness to support safer and more maintainable changes to HTTP transport functionality.
